• wavfile : string (The .wav extension is appended if no extension is given)
• Fs : integer, frequency sampling in Hz.

Description

Utility function to save .wav sound file. wavwrite(y,wavfile) writes a sound file specified by the string wavfile. The data should be arranged with one channel per column. Amplitude values outside the range [-1,+1] are ignored.
